MADRID – A Spanish trade union is suing a bakery that allegedly threw the severed arm of an employee into a bin after it was amputated in an accident with a kneading machine. The Workers Commissions said in a statement Wednesday that Bolivian immigrant Franns Rilles lost his left arm in May 28 at the Rovira bakery in the eastern Valencia region.

The union said that while Rilles was being taken to a hospital someone tossed his arm into the garbage. It says the bakery then cleaned the machinery and continued production.

Police found the arm the next day, the union said, but doctors were unable to reattach it.

The union said Rilles had worked illegally at the factory for two years, earning euro23 ($32) a day, and had not been properly trained on the kneading machinery.
